To all whom zitmay concern." v

Be itknown that I, CLYDE A. RIOKARD, a citizen of the United States,residing awarsonville, in the county ofSant'a Cruz and 5 Stateof'California, have invented new and useful Improvements inWatering-Troughs, of which the following is aspecification.

My invention relates to a trough for watering stock and'poultry. It'sobject is to provide a cheap, simple, practical, anddurable means forautomatically filling a trough or tank or maintaining its contents at auniform or approximately uniform level The invention consists of theparts and the construction and the combination of parts ashereinaftermore *fully describedand'claimed having reference to theaccompanying drawings, in'which Figure 1 is a side elevation of astock'- watering trough 'showing the application of" my automaticfilling-regulator; Fig. 2 is a side elevation of the poultry-wateringtrough. Fig. 3 i'sa plan viewof' same.

. Fig. 4 is an enlarged longitudinal section of thevalve. Fig; 5 shows amodified'form of that in Fig. 1'.

A representsa trough of considerable size, such as i's'usedfor-"watering stock and the like, pivoted to one side of its center, asat 2", to 'a suitable frame 31 The end-of the trough on the otherside ofitscenter from pivot 2 is connected with a valve or gate controlling thefee'dofwater to thetrough from the su ply-pipe or'conduit 4, so thatthis end of'tl ie trough may be raised more or less to vary thedifference in weight of the-wateron the two sides of pivot 2,.theopeningand closing of the valve being governed by such differenceinweight; As shown in this type of the apparatus, a: coil=spring 5 hasone endconnectedto the endof the trough farthest removedfrom'the-fulcrum 2, and;theother end ofthe springc'onnects to aboltor'rturnbuckle 6. The'latter connects with a bail orstirrup 7, whichlies over and embraces a short piece of hose or rubber tubing 8, whichis slipped over'and'secured at oneend' to the pipe 4, Fig. 4'.

r'ated'along'the top, as at 9, to provide an outlet for the water.slipped over the pipe so as tocover the outlet-port 9, the latterbeing-intermediate of Pipe4 isclosed at the end, but is perfo-' Thehose-section 8 is the ends of the hose, with theinner end of the hosesecured tight all'aroundt'ogthepi e by meansofa'wire or otherfasteningan with the opposite endof the hose-projecting more or less beyond theend of the pipe; I As the interior diameter of. the hose is a'littlelarger than the'exterior diameter'of theclosed end of the' pipe, itis'po'ssiblefor the water to flow throughport 9 into the trough when thehoseis not pressed down over'thehole 4.

The underside of the top of the bail has a downwardly-projecting bossarranged inline with theport, so that whenthe bail is pressedwith'suflicient weight down onto the hose the port 9 will be closedandthe further flow of water into the tank from ipe' 4 will be checked;Lifting the bail re eases the pressurefof the hoseoversthe hole andallows the flow of water to be resumed.

The sprin connections between the'hose' and bailare for the purpose ofchanging the inclinationof the trough relative to a horizontal plane, soas to afiect the diiference'in weight of the water on the two sides ofthe pivots'2 tovary the level at which the water in'the tank will automatica'lly close the valve. Thus if the turnbuckle. is operated tolift that end of the tank it will tend to equalize the quantity of waterin-the twoends of the tank. Conse quently it will require the admissionof more .waterinto the tank to create a suflicientand turnbuckle" orequivalent pressur'e'onthe bail to-close'the' valve, or if g theturnbuckle is turned in the opposite directionto depress that end ofthetank a less quantity of waterwill be required in the tank to operatethe-valve. The-purpose of thus varying the normallevelof the'water inthe tank is to enable the stockmanto kee' practically only fresh waterin the tank, caving only a comparatively small quantity in the tank tobecome heatedby the sunor to be come contaminated.

The frame which supports thetroughis mately with the length and breadthof the trough and connected direct to the supplypipe 41 The same sort ofa valve is used in this device as that shown and described in connectionwith Fig. 1, and the flow of the water through the valve is controlledby a bail 7, connected with one end of the trough. The opposite end ofthe trough is pivotally supported more or less proximate to the centerof the trough by a shiftable bail 11, which has its ends bent inwardover the frame 3 and extends beneath the trough and is engageable incorrugations 12 on the bottom of the trough. Suitable guides 13, carriedby the end of the trough opposite the feedipe, are adapted to engage theend of the i fame 3 so as to prevent longitudinal movement of the troughand to insure the bail 7 exerting pressure in the pro er manner on thehosesection 8 to contro the flow of water into the trough. The bail 11may be shifted back and forth on the top of the frame and on the bottomof the trough to engage any one or the other of the corrugations 12 tovary the difference in weight of the water on the two sides of thepivot-support 11. If a greater pressure is needed to close the valve orif it is desired to have the trough contain a less amount of water, thebail 11 is shifted away from the feed end of the trough, and vice versa.

In both forms of the apparatus shown one end of the trough is supportedby the valve and the other end has a suitable pivotal support, theprinciple of operation and of tie regulation of the flow of water beingthe same in each case.

While I have described a special form of valve which is very simple andthe parts of which can be easily obtained almost anywhere, I do not wishto. be considered as lim iting myself to this special form of valve,since there is a great variety of valves capable of performing the samefunctions as this one.

It is possible that various other changes may be made in my inventionwithout departing from the principle thereof, and I do not wish to beunderstood as limiting myself beyond the reasonable construction of myclaims. Thus in Fig. 5 is shown a modified form of valve mechanismespecially adapted for large tanks such as are used for watering stock.In this case a form of globe and angle-valve is used in which the valve9 is normally held open by a spring 9. The bail 7 bears on the valve andsupports the tank.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. The combination with a trough pivot- .ally mounted between its ends,of a supplypipe having a lateral discharge-port, a compressible tubeinclosing the delivery end of the supply-pipe and adapted to extend overthe trough, a bail embracing the compressible tube, and means connectingthe ball with the trough whereby upon the tilting of the trough the bailcompresses the exterior tube over the delivery-port'of the supply-pipe.

2. The combination with a trough pivotally mounted between its ends, ofa supplypipe having a lateral discharge-port, a tube of compressiblematerial fitted over the end of the supply-pipe and having a diameter inexcess of that of the end of the supply-pipe,

,said compressible tube extending over the trough,- a bail inclosing theexterior of the compressible tube, and means connecting the bail withthe trough whereby as the trough is tilted the bail is operated tocompress the exterior tube over the port of the discharge end of thesupply-pipe.

3. The combination with a trough pivotally mounted between its ends, ofa supplypipe having a lateral discharge-port, a tube extending over saidport and beyond the end of the supply-piae and over said trough, avertically-operab e valve, a bail iitting over the valve and exterior ofthe tube, and a spring connected with the bail, said spring connectingwith the trough, and. means connecting with the spring for changing theinclination of the trough relative to a horizontal plane.

4. The combination with a trough pivotally mounted between its ends, ofa supplypipe having a lateral port, a compressible tube inclosing theend of the discharge-pipe, and extending beyond said pipe, a bailsubstantially inclosing the compressible pipe and having a boss arrangedin line above said port, and means connecting the bail to the troughwhereby when the latter is tilted said boss compresses the tube oversaid lateral port.

5. The combination with a tilting trough and valve-controlled means forsupplying water thereto, said means being controlled by the movements ofthe trough, of a stationary frame extending around the sides and ends ofthe trough, and a guide on the trough. adapted to engage an end bar ofthe frame to prevent longitudinal movement of the trough.

6. The combination with a trough and valve-controlled means forsupplying water thereto, said means being controlled by the trough, of aframe including bars extending along the upper sides of the trough, abail shiftable on said bars, and a rack-surface on the trough with whichthe bail engages to shift the fulcrum-point of said trough.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
